与SL操作有关的资源(例如时域资源，又如频域资源，又如码域资源)的分配方式可以分类如下：The allocation of resources related to SL operations (for example, time domain resources, frequency domain resources, and code domain resources) can be classified as follows:
●模式1(Mode 1)：基站调度用于SL传输的SL资源。●Mode 1 (Mode 1): The base station schedules SL resources for SL transmission.
●模式2(Mode 2)：UE确定用于SL传输的SL资源(即基站不 参与SL资源的调度)。例如，执行SL传输操作的UE自主确定用于SL传输的SL资源。●Mode 2: The UE determines the SL resources used for SL transmission (that is, the base station does not participate in the scheduling of SL resources). For example, the UE performing the SL transmission operation autonomously determines the SL resources used for the SL transmission.
UE可以通过SCI(Sidelink Control Information，直行控制信息)调度数据的传输。SL操作可以支持“两阶段SCI”(two-stage SCI)，其中第一阶段SCI(1 st-stage SCI)可以包含资源预留和/或资源分配等信息，以便于所有正在监测(monitor)SL链路的UE对于资源预留和/或资源分配情况进行检测(sensing)；第二阶段SCI(2 nd-stage SCI)可以包含其他信息，例如和HARQ反馈相关的信息等。下文中如未特别说明，在单独提到“SCI”时，可以只包括第一阶段SCI，也可以只包括第二阶段SCI，也可以既包括第一阶段SCI也包括第二阶段SCI。 The UE can schedule data transmission through SCI (Sidelink Control Information). SL operation can support "two-stage SCI" (two-stage SCI), in which the first stage SCI (1 st -stage SCI) can contain information such as resource reservation and/or resource allocation, so that all monitoring (monitor) SL The UE of the link performs sensing for resource reservation and/or resource allocation; the second-stage SCI (2 nd- stage SCI) may contain other information, such as information related to HARQ feedback. If not specifically stated below, when “SCI” is mentioned separately, it may include only the first stage SCI, or only the second stage SCI, or both the first stage SCI and the second stage SCI.
第一阶段SCI的格式可以是SCI格式0-1(或者写成“SCI格式0_1”)。下面是SCI格式0-1中可以包含的信息的一些例子：The format of the first stage SCI can be SCI format 0-1 (or written as "SCI format 0_1"). The following are some examples of the information that can be included in the SCI format 0-1:
●优先级(Priority)。●Priority.
●频率资源分配(Frequency resource assignment)。●Frequency resource assignment.
●时间资源分配(Time resource assignment)。●Time resource assignment.
●资源预留周期(Resource reservation period)。●Resource reservation period.
●第二阶段SCI格式(2 nd-stage SCI format)。 ●The second stage SCI format (2 nd -stage SCI format).
第二阶段SCI的格式可以是SCI格式0-2(或者写成“SCI格式0_2”)。下面是SCI格式0-2中可以包含的信息的一些例子：The format of the second stage SCI can be SCI format 0-2 (or written as "SCI format 0_2"). The following are some examples of the information that can be included in SCI format 0-2:
●源层一标识符(Source Layer-1 ID，或者称为Layer-1 Source ID，层一源标识符，或者称为Physical Layer Source ID，物理层源标识符，或者(在上下文清楚的情况下)称为Source ID，源标识符)。●Source Layer-1 ID, or Layer-1 Source ID, or Physical Layer Source ID, or Physical Layer Source ID, or (when the context is clear ) Is called Source ID, source identifier).
●目标层一标识符(Destination Layer-1 ID，或者称为Layer-1 Destination ID，层一目标标识符，或者称为Physical Layer Destination ID，物理层目标标识符，或者(在上下文清楚的情况下)称为Destination ID，目标标识符)。●Destination Layer-1 ID, or Layer-1 Destination ID, Layer-1 Destination ID, or Physical Layer Destination ID, Physical Layer Destination ID, or (under clear context ) Is called Destination ID, target identifier).
●HARQ进程标识(HARQ Process ID)，或者说HARQ进程号(HARQ Process Number)。● HARQ Process ID (HARQ Process ID), or HARQ Process Number (HARQ Process Number).
●新数据标识(New Data Indicator，NDI)。●New Data Indicator (NDI).
●冗余版本(Redundancy Version，RV)。● Redundancy Version (Redundancy Version, RV).
第一阶段SCI可以携带在PSCCH上。第二阶段SCI可以和要传输的数据一起复用在PSCCH关联的(或者说调度的)PSSCH上。PSCCH及其所关联的PSSCH可以通过一定的方式复用在为SL传输分配的时域和/或频域资源上(例如，PSCCH的起始资源块所在的子信道是其所关联的PSSCH的起始子信道。又如，PSCCH的起始资源块是其所关联的PSSCH的起始子信道的起始资源块)。另外，可以认为第一阶段SCI和/或相应的第二阶段SCI调度了PSSCH(或者说调度了PSSCH的传输，或者说调度了PSSCH中携带的TB的传输)。The first stage SCI can be carried on the PSCCH. The second stage SCI can be multiplexed with the data to be transmitted on the PSSCH associated with the PSCCH (or scheduled). The PSCCH and its associated PSSCH can be multiplexed on the time domain and/or frequency domain resources allocated for SL transmission in a certain manner (for example, the subchannel where the starting resource block of the PSCCH is located is the start of the PSSCH associated with it. Starting subchannel. For another example, the starting resource block of the PSCCH is the starting resource block of the starting subchannel of the PSSCH to which it is associated). In addition, it can be considered that the first stage SCI and/or the corresponding second stage SCI schedules the PSSCH (or the transmission of the PSSCH is scheduled, or the transmission of the TB carried in the PSSCH is scheduled).
对于一个特定的包含PSCCH和/或PSSCH的SL传输，发送方可以称为TX UE，接收方可以称为RX UE。若所述SL传输是一个组播(groupcast)传输，或者单播(unicast)传输，在启用HARQ反馈的情况下，RX UE发送的PSFCH可以携带对TX UE发送的PSCCH和/或PSSCH的反馈，其中，所述反馈可以称为“HARQ-ACK信息”。在一些配置下，HARQ-ACK信息可以是肯定应答(ACK)，或者否定应答(NACK，或者NAK，Negative Acknowledgement)；在另一些配置下，HARQ-ACK信息可以只包含NACK。For a specific SL transmission including PSCCH and/or PSSCH, the sender may be referred to as TX UE, and the receiver may be referred to as RX UE. If the SL transmission is a groupcast transmission or unicast transmission, in the case of enabling HARQ feedback, the PSFCH sent by the RX UE may carry feedback on the PSCCH and/or PSSCH sent by the TX UE. Wherein, the feedback may be referred to as "HARQ-ACK information". In some configurations, the HARQ-ACK information may be an acknowledgement (ACK) or a negative acknowledgement (NACK, or NAK, Negative Acknowledgement); in other configurations, the HARQ-ACK information may only include NACK.
在时域，PSFCH资源可以在一个资源池中周期性地出现，例如通过参数sl-PSFCH-Period-r16进行配置(例如，配置为1个时隙，或者2个时隙，或者4个时隙)。参数sl-PSFCH-Period-r16的一个特殊的取值(例如0)可以用于指示相应的资源池中没有配置PSFCH资源，和/或表示相应的资源池中HARQ反馈被禁用。与PSFCH周期有关的时隙可以是“逻辑时隙”，即只包括属于相应的资源池中的时隙；例如，在某个帧(frame)中的时隙0和时隙5属于某个资源池的时域资源，而时隙1、2、3和4不属于该资源池的时域资源，则sl-PSFCH-Period-r16＝1可以指示上述时隙0和时隙5中存在PSFCH资源。In the time domain, PSFCH resources can appear periodically in a resource pool, for example, configured by the parameter sl-PSFCH-Period-r16 (for example, configured as 1 time slot, or 2 time slots, or 4 time slots ). A special value (for example, 0) of the parameter sl-PSFCH-Period-r16 may be used to indicate that no PSFCH resource is configured in the corresponding resource pool, and/or to indicate that HARQ feedback in the corresponding resource pool is disabled. The time slots related to the PSFCH period can be "logical time slots", that is, only time slots that belong to the corresponding resource pool are included; for example, time slot 0 and time slot 5 in a certain frame belong to a certain resource The time domain resources of the pool, and time slots 1, 2, 3, and 4 do not belong to the time domain resources of the resource pool, then sl-PSFCH-Period-r16=1 can indicate that there are PSFCH resources in the above time slots 0 and 5 .
在频域，PSFCH资源可以配置在一个RB集合(例如一组连续PRB的集合，又如一组部分或全部不连续的PRB的集合)中，例如通过参数sl-PSFCH-RB-Set进行配置。In the frequency domain, the PSFCH resource can be configured in an RB set (for example, a set of continuous PRBs, or a set of partially or completely discontinuous PRBs), for example, configured through the parameter sl-PSFCH-RB-Set.
另一方面，5G(或者称为NR，或者称为5G NR)可以通过DCI(Downlink Control Information，下行控制信息)调度PDSCH(Physical Downlink Shared Channel，物理下行共享信道)上的下行传输以及PUSCH(Physical Uplink Shared Channel，物理上行共享信道)上的上行传输。在5G V2X中，还可以额外地通过DCI调度PSCCH和PSSCH的传输。On the other hand, 5G (or NR, or 5G NR) can schedule downlink transmission on PDSCH (Physical Downlink Shared Channel) and PUSCH (Physical Downlink Shared Channel) through DCI (Downlink Control Information). Uplink Shared Channel, physical uplink shared channel). In 5G V2X, the transmission of PSCCH and PSSCH can be additionally scheduled through DCI.
5G支持多种DCI格式，例如，可以包括表1所示的DCI格式。每种DCI格式的CRC可以用一个RNTI(Radio-Network Temporary Identifier，无线网络临时标识符)加扰，以指示一个特定的用途和/或一个或多个目的UE。例如，用于指示寻呼(paging)的DCI格式的CRC可以用P-RNTI加扰。5G supports multiple DCI formats, for example, the DCI formats shown in Table 1 may be included. The CRC of each DCI format can be scrambled with an RNTI (Radio-Network Temporary Identifier) to indicate a specific purpose and/or one or more target UEs. For example, the CRC used to indicate the DCI format of paging may be scrambled with P-RNTI.

5G的DCI可以承载在PDCCH(Physical Downlink Control Channel，物理下行控制信道)上。一个PDCCH可以由一个或者多个CCE(control-channel element，控制信道元素)组成，而一个CCE又可以由多个(例如，6个)REG(resource-element group，资源元素组)组成，而REG则在CORESET(control-resource set，控制资源集)内定义。一 个CORESET在频域包含多个资源块(每个资源块由频域上12个连续的子载波组成)，在时域上包含一个或者多个(例如，1个，或者2个，或者3个)OFDM符号。The 5G DCI can be carried on the PDCCH (Physical Downlink Control Channel). A PDCCH can be composed of one or more CCEs (control-channel elements, control channel elements), and a CCE can be composed of multiple (for example, 6) REGs (resource-element groups), and REG It is defined in CORESET (control-resource set). A CORESET contains multiple resource blocks in the frequency domain (each resource block consists of 12 consecutive subcarriers in the frequency domain), and contains one or more (for example, 1, or 2, or 3) in the time domain ) OFDM symbol.
UE可以在一个或者多个搜索空间集合(search space set)上监听基站的PDCCH传输，其中，每个搜索空间集合可以对应一组PDCCH候选(PDCCH candidate)。UE通过在所要监听的PDCCH候选对应的时频资源上进行盲检(blind detection)以确定是否存在发给自己的PDCCH。The UE may monitor the PDCCH transmission of the base station on one or more search space sets (search space sets), where each search space set may correspond to a set of PDCCH candidates (PDCCH candidates). The UE performs blind detection on the time-frequency resource corresponding to the PDCCH candidate to be monitored to determine whether there is a PDCCH sent to itself.
搜索空间集合可以分为CSS(Common Search Space，公共搜索空间)集合和USS(UE-specific search space，UE特定搜索空间)集合，例如，具体地，可以定义下面的搜索空间集合中的一个或多个：The search space collection can be divided into a CSS (Common Search Space) collection and a USS (UE-specific search space, UE-specific search space) collection. For example, specifically, one or more of the following search space collections can be defined indivual:
●类型0-PDCCH CSS集合。例如通过MIB中的pdcch-ConfigSIB1参数进行配置，或者通过PDCCH-ConfigCommon中的searchSpaceSIB1参数进行配置，或者通过PDCCH-ConfigCommon中的searchSpaceZero参数进行配置。用于加扰相应的DCI格式的CRC的RNTI可以包括SI-RNTI。可以用于MCG(Master Cell Group，主小区组)的主小区(primary cell)。●Type 0-PDCCH CSS collection. For example, it is configured through the pdcch-ConfigSIB1 parameter in the MIB, or through the searchSpaceSIB1 parameter in the PDCCH-ConfigCommon, or through the searchSpaceZero parameter in the PDCCH-ConfigCommon. The RNTI used to scramble the CRC of the corresponding DCI format may include SI-RNTI. It can be used for the primary cell of MCG (Master Cell Group, primary cell group).
●类型0A-PDCCH CSS集合。例如通过PDCCH-ConfigCommon中的searchSpaceOtherSystemInformation参数进行配置。用于加扰相应的DCI格式的CRC的RNTI可以包括SI-RNTI。可以用于MCG的主小区。●Type 0A-PDCCH CSS collection. For example, it is configured through the searchSpaceOtherSystemInformation parameter in PDCCH-ConfigCommon. The RNTI used to scramble the CRC of the corresponding DCI format may include SI-RNTI. Can be used for MCG's primary cell.
●类型1-PDCCH CSS集合。例如通过PDCCH-ConfigCommon中的ra-SearchSpace参数进行配置。用于加扰相应的DCI格式的CRC的RNTI可以包括RA-RNTI、TC-RNTI。可以用于主小区。●Type 1-PDCCH CSS collection. For example, it is configured through the ra-SearchSpace parameter in PDCCH-ConfigCommon. The RNTI used to scramble the CRC of the corresponding DCI format may include RA-RNTI and TC-RNTI. Can be used for the primary cell.
●类型2-PDCCH CSS集合。例如通过PDCCH-ConfigCommon中的pagingSearchSpace参数进行配置。用于加扰相应的DCI格式的CRC的RNTI可以包括P-RNTI。可以用于MCG的主小区。●Type 2-PDCCH CSS collection. For example, it is configured through the pagingSearchSpace parameter in PDCCH-ConfigCommon. The RNTI used to scramble the CRC of the corresponding DCI format may include P-RNTI. Can be used for MCG's primary cell.
●类型3-PDCCH CSS集合。例如通过PDCCH-Config中的SearchSpace配置，其中searchSpaceType＝common。用于加扰相应的DCI格式的CRC的RNTI可以包括INT-RNTI、SFI-RNTI、 TPC-PUSCH-RNTI、TPC-PUCCH-RNTI、TPC-SRS-RNTI、C-RNTI、MCS-C-RNTI和CS-RNTI，其中C-RNTI、MCS-C-RNTI和CS-RNTI可以只用于主小区。●Type 3-PDCCH CSS collection. For example, through the SearchSpace configuration in PDCCH-Config, where searchSpaceType=common. The RNTI used to scramble the CRC of the corresponding DCI format may include INT-RNTI, SFI-RNTI, TPC-PUSCH-RNTI, TPC-PUCCH-RNTI, TPC-SRS-RNTI, C-RNTI, MCS-C-RNTI, and CS-RNTI, where C-RNTI, MCS-C-RNTI and CS-RNTI can only be used for the primary cell.
●USS集合。例如通过PDCCH-Config中的SearchSpace配置，其中searchSpaceType＝ue-Specific。用于加扰相应的DCI格式的CRC的RNTI可以包括C-RNTI、MCS-C-RNTI、SP-CSI-RNTI、CS-RNTI、SL-RNTI、SL-CS-RNTI和SL-L-CS-RNTI。●USS collection. For example, through the SearchSpace configuration in PDCCH-Config, where searchSpaceType=ue-Specific. The RNTI used to scramble the CRC of the corresponding DCI format may include C-RNTI, MCS-C-RNTI, SP-CSI-RNTI, CS-RNTI, SL-RNTI, SL-CS-RNTI, and SL-L-CS- RNTI.
有时候可以使用“搜索空间”(search space)的概念。搜索空间可以关联到搜索空间集合，例如，一个搜索空间可以定义为一个搜索空间集合的一部分，或者说子集(例如对应一组PDCCH候选中聚合等级相同的PDCCH候选)；又如，一个搜索空间等同于一个搜索空间集合；又如，按其他方式定义搜索空间和搜索空间集合的关系。Sometimes the concept of "search space" can be used. A search space can be associated with a search space set. For example, a search space can be defined as a part of a search space set, or a subset (for example, corresponding to PDCCH candidates with the same aggregation level in a set of PDCCH candidates); for another example, a search space It is equivalent to a search space collection; another example is to define the relationship between the search space and the search space collection in other ways.
由于UE在一个特定的搜索空间中监听DCI，“DCI格式”的定义可以认为与监听DCI的搜索空间有关。例如，有时候(例如在计算需要监听的DCI大小的数量时)可以认为“在搜索空间1中监听的DCI格式x”和“在搜索空间2中监听的DCI格式x”是两种不同的DCI格式。Since the UE monitors the DCI in a specific search space, the definition of "DCI format" can be considered related to the search space for monitoring the DCI. For example, sometimes (for example, when calculating the number of DCI sizes that need to be monitored), it can be considered that "DCI format x monitored in search space 1" and "DCI format x monitored in search space 2" are two different DCIs. Format.
一个搜索空间中可以监听的DCI格式可以有一定的限制。例如，一个UE特定搜索空间可以配置为监听DCI格式0_0和DCI格式1_0，或者配置为监听DCI格式0_1和DCI格式1_1，但不可以配置为监听DCI格式0_0、DCI格式1_0、DCI格式0_1和DCI格式1_1。There may be certain restrictions on the DCI formats that can be monitored in a search space. For example, a UE-specific search space can be configured to monitor DCI format 0_0 and DCI format 1_0, or configured to monitor DCI format 0_1 and DCI format 1_1, but cannot be configured to monitor DCI format 0_0, DCI format 1_0, DCI format 0_1 and DCI Format 1_1.
有些DCI格式(例如DCI格式3_0，又如DCI格式3_1，等等)只配置为在用户特定搜索空间中监听，而不配置为在公共搜索空间中监听。对于一个这样的DCI格式(记为DCI格式X)，“UE配置为监听DCI格式X”等同于“UE配置为在一个用户特定搜索空间中监听DCI格式X”。Some DCI formats (for example, DCI format 3_0, and DCI format 3_1, etc.) are only configured to monitor in the user-specific search space, but not configured to monitor in the public search space. For such a DCI format (denoted as DCI format X), "the UE is configured to monitor the DCI format X" is equivalent to "the UE is configured to monitor the DCI format X in a user-specific search space".
UE在盲检PDCCH候选时需要假定一个DCI大小(DCI size)。由于处理能力的限制，UE在每个时隙只能监听一定数量的DCI大小，例如，小区中配置的不同DCI大小的总数不超过4个；又如，小区中配置的与C-RNTI有关(例如，相应的DCI格式的CRC由C-RNTI加扰)的不同DCI大小的总数不超过3个。The UE needs to assume a DCI size (DCI size) when blindly detecting PDCCH candidates. Due to the limitation of processing capacity, the UE can only monitor a certain number of DCI sizes in each time slot. For example, the total number of different DCI sizes configured in the cell does not exceed 4; for another example, the configuration in the cell is related to C-RNTI ( For example, the total number of different DCI sizes of the corresponding DCI format CRC is scrambled by C-RNTI does not exceed 3.
一个DCI格式中各个字段的定义(例如，该字段是否出现，以及该 字段的大小，等等)可以随着加扰所述DCI格式的CRC的RNTI的不同而不同。另一方面，DCI格式的设计可以使得当使用两个或者更多个或者所有适用的RNTI分别加扰一个DCI格式的CRC时，所述DCI格式的大小是一样的。例如，表2和表3分别显示了使用SI-RNTI和RA-RNTI加扰其CRC时DCI格式1_0中各个字段的定义的一个例子；可以看到，通过分别为这两种情况定义不同的“保留比特”字段的大小，DCI格式1_0的大小可以统一写成28+d FDRA，其中d FDRA是频域资源分配字段的大小。d FDRA的值可以与监视所述DCI格式的搜索空间有关。 The definition of each field in a DCI format (for example, whether the field appears, and the size of the field, etc.) may be different according to the RNTI that scrambles the CRC of the DCI format. On the other hand, the design of the DCI format can be such that when two or more or all applicable RNTIs are used to scramble the CRC of one DCI format, the size of the DCI format is the same. For example, Table 2 and Table 3 respectively show an example of the definition of each field in DCI format 1_0 when SI-RNTI and RA-RNTI are used to scramble its CRC; it can be seen that by defining different " The size of the "reserved bits" field, the size of the DCI format 1_0 can be uniformly written as 28+d FDRA , where d FDRA is the size of the frequency domain resource allocation field. The value of d FDRA may be related to the search space for monitoring the DCI format.
一个DCI格式中各个字段的定义还可以与其他预定义、配置或预配置信息有关。为确定一个DCI格式(例如记为DCI格式X)的大小，首先需要“确定DCI格式X”，即根据预定义、预配置或配置信息确定所述DCI格式X中出现的每一个字段(例如，确定该字段是否出现，以及该字段的大小，等等)。可选地，在“确定DCI格式X”后，所述DCI格式X的大小可以称为所述DCI格式X的“信息比特的数量”。可选地，在对所述DCI格式X进行过任何DCI大小对齐操作(例如添加零填充比特)后，不再称所述DCI格式X的大小为其“信息比特的数量”。The definition of each field in a DCI format may also be related to other predefined, configuration or pre-configuration information. In order to determine the size of a DCI format (for example, DCI format X), it is first necessary to "determine DCI format X", that is, to determine each field appearing in the DCI format X (for example, Determine whether the field appears, and the size of the field, etc.). Optionally, after "determining the DCI format X", the size of the DCI format X may be referred to as the "number of information bits" of the DCI format X. Optionally, after any DCI size alignment operation (for example, adding zero padding bits) is performed on the DCI format X, the size of the DCI format X is no longer called the "number of information bits".
为了尽量减少小区中总的DCI大小的数量，DCI格式的设计可以使得在两个或者更多个公共搜索空间中监听的同一个DCI格式的大小是一样的，和/或使得在两个或者更多个用户特定的搜索空间中监听的同一个DCI格式的大小是一样的。此时，可选地，在提及一个DCI格式x的大小时，可以忽略具体是哪一个搜索空间，例如，可以说“在公共搜索空间中监听的DCI格式x的大小”，又如，可以说“在UE特定搜索空间中监听的DCI格式x的大小”。In order to minimize the number of total DCI sizes in a cell, the design of the DCI format can make the size of the same DCI format monitored in two or more common search spaces the same, and/or make the size of the same DCI format monitored in two or more common search spaces. The size of the same DCI format monitored in multiple user-specific search spaces is the same. At this time, optionally, when referring to the size of a DCI format x, you can ignore the specific search space. For example, you can say "the size of the DCI format x monitored in the public search space". Say "the size of the DCI format x monitored in the UE specific search space".
